US Patent 11885918 Sonar system with dynamic power steering

A sonar array system comprises a plurality of sonar arrays and a sonar signal processor. Each sonar array is configured to receive transmit electronic signals and transmit corresponding sonar beams in a forward direction and a downward direction. Each sonar array includes a plurality of groups of sonar transducer elements, with each group including at least a first sonar transducer element and a second sonar transducer element. The sonar signal processor is configured to communicate a plurality of transmit electronic signals to the sonar arrays. The transmit electronic signals include a first transmit electronic signal including a periodic waveform having a first phase and a second transmit electronic signal including a periodic waveform having a second phase. A distribution of power between the sonar beams transmitted in the forward direction and in the downward direction varies according to a difference in the first phase and the second phase.
